The following image is created by POVray and is from the University of Lethbridge. It's standing ouside the Study Centre looking at W-Building around the afternoon.
In building this image, I emphasized on the reflection of window. The sunshine is kind of strong in spring especially in the afternoon. Therefore, it makes windows look like mirrors. From the reflection of window we can see some scene of the other side such as stairs, hills and coulees.
The hills and coulees were done with height-field, the building is a series of transformed boxes, put together in a group. The light source is mixed with gold and white. Also, the clouds will put the shadows on the hill. The camera is closed to the ground looking up the sky
